From: Jeff Johnson Date: Tue, 5 Mar 2024 15:14:00 +0000 (-0800) Subject: wifi: ath11k: fix soc_dp_stats debugfs file permission X-Git-Tag: v6.10-rc1~153^2~363^2^2~25 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=fa645e663165d69f05f95a0c3aa3b3d08f4fdeda;p=thirdparty%2Flinux.git wifi: ath11k: fix soc_dp_stats debugfs file permission Currently the soc_dp_stats debugfs file has the following permissions: # ls -l /sys/kernel/debug/ath11k/pci-0000:03:00.0/soc_dp_stats -rw------- 1 root root 0 Mar 4 15:04 /sys/kernel/debug/ath11k/pci-0000:03:00.0/soc_dp_stats However this file does not actually support write operations -- no .write() method is registered. Therefore use the correct permissions when creating the file. After the change: # ls -l /sys/kernel/debug/ath11k/pci-0000:03:00.0/soc_dp_stats -r-------- 1 root root 0 Mar 4 15:15 /sys/kernel/debug/ath11k/pci-0000:03:00.0/soc_dp_stats Tested-on: WCN6855 hw2.1 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.30 Signed-off-by: Jeff Johnson Signed-off-by: Kalle Valo Link: https://msgid.link/20240305-fix-soc_dp_stats-permission-v1-1-2ec10b42f755@quicinc.com --- diff --git a/drivers/net/wireless/ath/ath11k/debugfs.c b/drivers/net/wireless/ath/ath11k/debugfs.c index a48e737ef35d6..414a5ce279f78 100644 --- a/drivers/net/wireless/ath/ath11k/debugfs.c +++ b/drivers/net/wireless/ath/ath11k/debugfs.c @@ -1,7 +1,7 @@ // SPDX-License-Identifier: BSD-3-Clause-Clear /* * Copyright (c) 2018-2020 The Linux Foundation.
